Indecomposable primarily comultiplication modules over a pullback of two Dedekind domains

S. Ebrahimi Atani, F. Esmaeili Khalil Saraei (2010)

Colloquium Mathematicae

Similarity:

We describe all those indecomposable primarily comultiplication modules with finite-dimensional top over pullback of two Dedekind domains. We extend the definition and results given by R. Ebrahimi Atani and S. Ebrahimi Atani [Algebra Discrete Math. 2009] to a more general primarily comultiplication modules case.

On large selforthogonal modules

Commentationes Mathematicae Universitatis Carolinae

Similarity:

We construct non faithful direct summands of tilting (resp. cotilting) modules large enough to inherit a functorial tilting (resp. cotilting) behaviour.
